Are megaquakes clustered? [PDF]
, 2012 We study statistical properties of the number of large earthquakes over the past century. We analyze the cumulative distribution of the number of earthquakes with magnitude larger than threshold M in time interval T, and quantify the statistical ...

The hidden simplicity of subduction megathrust earthquakes
Science, 2017 Universal scaling for big quakes The amount of energy released as a large fault ruptures provides some clues about the overall size of an earthquake. Meier et al. looked at this energy release for more than 100 large earthquakes.

Partial Ruptures, Cascading Multi‐Fault Ruptures, and Aftershocks in 2D Random Fault Network
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The Gutenberg‐Richter law for the distribution of earthquake magnitude and the Omori law for the decay of aftershocks are two universal laws in seismicity. Although numerical models have been developed to reproduce these laws, they sometimes produce many more foreshocks and fewer aftershocks than observed.

The 25 October 2010 Mentawai tsunami earthquake (M_w 7.8) and the tsunami hazard presented by shallow megathrust ruptures [PDF]
, 2011 The 25 October 2010 Mentawai, Indonesia earthquake (M_w 7.8) ruptured the shallow portion of the subduction zone seaward of the Mentawai islands, off-shore of Sumatra, generating 3 to 9 m tsunami run-up along southwestern coasts of the Pagai Islands that

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Laboratory experiments and theoretical models suggest that earthquakes are preceded by extended nucleation phases, perhaps by slow but accelerating slip. However, such nucleation phases are hard to observe before natural earthquakes. Here we identify clustered foreshock sequences that could be nucleation signatures.

Probabilistic tsunami hazard analysis of Batukaras, a tourism village in Indonesia [PDF]
Natural Hazards and Earth System SciencesIndonesia's location in the middle of tectonic plates makes it vulnerable to earthquakes and tsunamis, especially in the megathrust zone around the island of Sumatra and the southern part of the island of Java.

Trench‐Breaching Rupture of the 2025 Mw 8.8 Kamchatka Earthquake and How It Repeats the 1952 Event
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The 29 July 2025 Mw 8.8 Kamchatka earthquake generated a trans‐Pacific tsunami. The hypocenter was nearly at the same location as the 1952 great earthquake (Mw 8.8–9.0). Determining whether the 2025 rupture reached the trench and how it relates to the 1952 event is crucial for understanding slip behavior along the Kamchatka subduction zone. We
